IBM x3850 X6. 2x Compute Book Xeon 15C E7-8880v2 130W 2.5GHz/1600MHz/37.5MB. 16x32GB. 6x1.2TB HS 2.5in SAS. 2x400GB HS 2.5in SATA SSD. SR M5210. 4x1400W p/s. Rack

The IBM System x3850 X6 and x3950 X6 servers are high-throughput, scalable, SMP-capable, 15-core Intel Xeon-based servers. They deliver excellent scalability for adding memory, adapter cards, or multiple processors.

Models are powered with multi-core Intel Xeon processors that use 64-byte cache lines. EMT64T architecture supports 64-bit extensions. Four connectors for Xeon MP processors on x3850 X6 and eight connectors for Xeon MP processors on the x3950 X6 standard on the system board. High-speed PC3L-12800 ECC SDRAM 1600 MHz memory provides excellent processor-to-memory subsystem performance.

The IBM System x3850 X6 and x3950 X6 system architecture is fine tuned and engineered to optimize the powerful Xeon processors. This architecture consists of the following components:

- 15-core Xeon processors
- System memory cards with Intel Scalable Memory Buffers
- Intel host-bridge I/O controllers

These Xeon processors use Intel Quick Path Interconnect busses for external operations. Each processor supports four independent busses to the memory, for a total of 64 Gbps of potential memory bandwidth per CPU.
